Dell EMC-S CPU Statistics Test

This test auto-discovers the stack units of the Dell EMC S-Series switch, and monitors the current CPU utilization of each stack unit. If the stack unit is found to consume CPU resources excessively, then, this test will help administrators to determine when exactly did the CPU utilization peak - during the last 5 sec? or 1 minute? or 5 minutes? This revelation helps administrators troubleshoot the CPU spikes better.

Target of the test : A Dell S-Series Switch

Agent deploying the test : An external Agent

Outputs of the test : One set of results for each stack unit:CPU core combination in the Dell EMC S-Series Switch to be monitored.

Configurable parameters for the test

Parameter	Description
Test Period	How often should the test be executed.
Host	The IP address of the host for which this test is to be configured.
SSH Username and SSH Password	Specify the credentials of a user who has the right to execute CLI (command-line interface) commands on the target switch and pull out metrics via SSH.
Confirm Password	Confirm the SSH Password by retyping it here.
SSH Port	The port at which the target switch exposes its SSH; The default value is 22.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Last 5 seconds CPU utilization	Indicates the percentage of CPU utilization of this stack unit during last 5 seconds.	Percent	By comparing the values of these measures, you can quickly figure out when exactly was the CPU usage maximum. Using this analysis, administrators can further investigate the real reason behind the sudden spike in the CPU usage.
Last 1 minute CPU utilization	Indicates the percentage of CPU utilization of this stack unit during last 1 minute.	Percent
Last 5 minutes CPU utilization	Indicates the percentage of CPU utilization of this stack unit during last 5 minutes.	Percent
